If you specify what the 18 is, than I will be able to give you a more accurate answer.
If it is 18 units in diameter that you are talking about, the radius is nine.
However, if you are talking about the circumfrence, you can find the diameter (which is 9) and:
9/π, which gives you 2.866242 units
*π is the greek letter pi, which is roughly about 3.14cm

if 18 is the diameter then the radius is 9

If the circumference is 18, the radius is 9/pi = 2.86
If the area is 18, the radius is 2.39.

what do you mean if a circle is 18? The diameter? The circumference? The area?

18-year circles can vary from 1 ft to 20 ft.

huh? you meant if the circumference of the circle is 18?
C = 2pi*r
18 = 2pi * r
r = 2.866242
